Could be, don't know. I can see how that would be less than useful. In 
that case you may need to use yet another object to track state (blech):

function clickied() {
    global $state;
     if ($state->wasClicked) {
       echo 'The button was already clickied!';
     } else {
       echo 'This is the first time the button was clicked!';
       $state->wasClicked = TRUE;
     }
}
